` Be it known that I, CARL AU'GUsrWoLL- Nien, subject ofthe King of-Bavaria, E1nplre of Germany,residing at No. 48 Amaf toma-tic starting and stoppingdevice for the actuating mechanism of'such machines. It

consists of two; catches so. arranged` andy combined that after one ofthem has been withdrawn by the weight of-`V the coin the.

otheris withdrawn by a spring, while the rengagementl of thehrst. catchV effects, the.l

rengagement of the second one through the said actuating mechanism.` `The construcf tion is such that the catch'controlled by the` coin is considerably relieved from the pressure of the actuating` mechanism and 1s,

Y therefore, easily movable.` I

En the-drawing, in which I. have illustrated my invention by way of example, Figure l shows theI position ofI the parts when at rest, the dotxandV dash lines: showing the parts when the machine is being operated; Fig. '2 shows the position of the parts at the moment when the machine `is to be automatically stoppedzr Y With one of the shafts of the machine, e. g. shaft a revolves the eccentric b. Shaft a 1s supposed to start" the various operations of the machine, such as unrolling and cut-` ting olf stampsfrom a roll, and during its rotation the eccentric b pushes out a slide (Z which each time is returned to its former position by a spring c. The speed of rotation of shaft a is regulated in a well-known manner by the vanes 7 on shaft Z to which a high speed is imparted by the gearing g, 7L, z', Ic. A stop m is secured to the hub of the vanes f. The lower arm o of a double lever 0, p pivoted at n is provided with a catch g, adapted to engage said stop m. To the upper arm p of the lever is secured a catch r adapted to move between two Xed stops s, s. A tension spring t exerts a constant pull on the lever arm 0, tending toV Withdraw Vthe catch g from stop m. The movement of the lever arm p is limited by a fixed pin u.

To the catch r is pivoted one end of a Srfaeefiei Off Letters Peten?- p Application mean-arch 25,1914.` seriaimisaaicr.

Over thefreeendof the lever arm' w is arranged a chute z, through which; the coin is delivered direct-lyon tomtheend of the' said leverlarm. The shaft av and the parts asso-` elatedy therewith are driven by the spring motor `Qshowrrm4 Fig.` l, which drives .a gear 3 being` in mesh with a gear hon the anisl of which Vis mounted a gearv 5, which gear 1n turn is in mesh with gear 6 fast on shaft a.

rlhe Voperation isK as follows: When the parts; are at rest the catch g `bears ,against stop m thus preventing shaft a from rotat ing. 'Ehefothercatch rj isheldin Vits upper end, position by the weighty/.0n lever arm the catch. r being'l held againstthe' free end of the "slide Z with sliglit friction. f It is the catch` q which has, to take up the forces which passalmost exactly through the pivot so that hardly On the other cia-ble pressure on= the catch r because the tension spring c acting on theV slide d tends topull it toward the left Fig. l, while thev4 outward: movementof theV slide d, i. e. thel movement toward the rightV in Fig. l is stopped, as soonV as the stop m is caught by catchrg. Therefore, when the parts are at rest, the catch 1 is very easily movable.

The weight' ofi the` coin falling through the chute z on to the lever arm fw, (the lever to, :u is preferably arranged as low as possible) causes the arm w to swing downward, at the same time lifting the weight c whereby the catch r is withdrawn from the slide CZ, through the rod o. The spring t now is able to pull the catch g out of the pathV of the stop m, the lever arm o assum. ing the position shown by the dot and dash lines, the lever arm p bearing against the fixed pin u. As soon as the coin has left the lever arm co, the lever arm descends, due to the weight y and through the rod 'v continuously forces the catch r upward against the slide cl, which at this moment is still moving toward the right in Fig. l.V But as the slide d starts to move to the left, the catch r will be moved to engage again the end face d of the slide al, in which position the catch r will be also in contact with the (Fig. 2). As the slide Z then returns into the position shown in Fig. 1 the catch r will remain in contact with the slide and during this time the spring t is stretched, while the catch Q islifted with the lever arm 0 back to its original position, where it engages stop m. Y Because of the easily movable catch 1 the machine will on a coin being dropped into the chute e, never fail to be set in motion, and on? account of the exceedingly simple arrangement, and coperation of the movable parts, will always be-autcmatically stopped, after exactly the same interval romthe time when it was started.

upper stop s Vhile my construction is suitable for allf automatic vending machines itis particu` larly adapted for machines for the automatic sale of postage stamps where the yworking parts must always come to rest at the precise moment, z'. c. when a stamp has been delivered.

I claim: Y Y 1. In automatic Vvending machines the combination with the actuating` mechanism and a slide operated thereby, oi2 a catch normally in Vcontact with said slide, a second catch normally in engagement with a membei' of said actuating mechanism holding it matically `at rest, aV connectinglink between'said -two catches, a spring acting on said second catch, and a coin-controlled member connected'with said lirst .catch so as to-autowithdraw the same upon a coin thereby permitting said spring to withdraw the second catchv and release the actuating and a slide operated thereby,
